Temperature-control device for a battery system

Abstract

The invention relates to a temperature-control device (1) for a battery system, at least comprising a cuboid-shaped hollow body (2) with at least one connection device (3) for supplying and at least one connection device (4) for discharging a separately temperature-controlled fluid, a plurality of regularly arranged and identically formed openings (7) extending from a first body surface (5) to a second body surface (6), wherein a cylindrical battery cell (8) is accommodated by each opening (7), so that a fluid-tight liquid space is formed, which is characterized in that the hollow body (2), excluding the cell head (11) and the cell bottom (12), extends over a height h of >20 to <100% of the total height H of the battery system.

The invention claimed is: 
     
       1. A temperature control device for a battery system, said temperature-control device comprising:
 a cuboid-shaped hollow body having a liquid space therein with at least one connection device configured to supply a separately temperature-controlled fluid to the liquid space and at least one connection device configured to discharge the separately temperature-controlled fluid, 
 the body having therein a plurality of regularly arranged and identically formed openings extending from a first body surface to a second body surface, 
 wherein each opening accommodates therein a respective cylindrical battery cell in a fluid-tight connection so that the fluid space in the hollow body is fluid-tight, and 
 wherein the hollow body, excluding the cell head and the cell bottom, extends over a height h of >20 to <100% of the total height H of the battery system. 
 
     
     
       2. A temperature control device for battery cells according to  claim 1 , wherein each opening has a sealing element that encloses the cylindrical battery cells. 
     
     
       3. A temperature control device for battery cells according to  claim 1 , wherein the cuboid-shaped hollow body is integrally made from plastic. 
     
     
       4. A temperature control device for battery cells according to  claim 1 , wherein the openings (are arranged in a densest circular packing form. 
     
     
       5. A temperature control device for battery cells according to  claim 1 , wherein the individual battery cells are spaced apart from each other. 
     
     
       6. A temperature control device for battery cells according to  claim 1 , wherein the separately temperature-controlled fluid is pumped in circulation via a heating and/or cooling device. 
     
     
       7. A temperature control device for battery cells  claim 1 , wherein the fluid is conductive. 
     
     
       8. A temperature control device for battery cells according to  claim 1 , wherein the cuboid-shaped hollow body is integrally made from POM. 
     
     
       9. A battery pack with temperature-control devices connected in series according to  claim 1 , wherein the separately temperature-controlled fluid is guided in circulation via temperature-control devices, at least one pumping device, and a heating and/or cooling device.
